Christine was not an angel, nor was she a demon, nor was she a witch or werewolf or any other sort of thing. There seemed to be an abundance of them in Colligo (or that's what the gossip was, anyway), but she'd never really noticed their presence. She didn't even know that the woman she was about to strike up a conversation with was Satan. She probably wouldn't believe it when she found out, either.
"Hi," She said amiably. Sometimes she just got curious about things and couldn't help not talking about them, especially when Martha was on duty and she wasn't (since Doctor McCoy had returned, they'd been allowed to have breaks to sleep and stuff). "I like your outfit." She added with a smile.
